Bullets in Luigi Mangione’s bag convinced police that he was UnitedHealthcare CEO killing suspect

Moments after Luigi Mangione was put in handcuffs at a Pennsylvania McDonald’s, a police officer searching his backpack found a loaded gun magazine wrapped in a pair of underwear. The discovery, recounted in court Monday as Mangione fights to exclude evidence from his New York murder case, convinced police in Altoona, Pennsylvania, that he was the man wanted for killing UnitedHealthcare CEO Brian Thompson in Manhattan five days earlier. Wasser, a 19-year Altoona police veteran, testified on the fourth day of a pretrial hearing as Mangione seeks to bar prosecutors from using the magazine and other evidence against him, including a 9 mm handgun and a notebook that were found during a subsequent search of the bag.
